The 36-year-old PhD student from the Microbiology department had allegedly attempted suicide at his residence in Gautam Nagar by overdosing on drugs on March 25 and had accused his supervisor of mental harassment, abuse and delay in his fellowship.
A Hindustan Times report states that when police arrested Khurram on Saturday, they were surprised by his "knowledge" of medicines, the names of doctors and department heads at AIIMS. He had accessed a diary issued to doctors.
Khurram, a native of Sitamarhi, Bihar, was attending to his sister being treated at AIIMS, but was apparently unsatisfied with the slow pace.
The reason as to why Khurran posed as a doctor at hospital is still unknown to the police because he has been constantly changing his statements during the police investigation. During questioning, he told police that he chose to pose as a doctor as his sister had to wait for ages to get an appointment with a doctor. One of the reasons he said he wanted he help one of his family members get better treatment through preferred doctors.
According to RDA president Harjit Singh, Khurram had been observing his activities in the campus for the past many months and made a decision to keep a watch. To assert his identity, he had even uploaded pictures on his social media accounts wearing a doctor's coat and a stethoscope around his neck.
The police said Khurram had no criminal record.
The chief resident Doctor's Association, Harjit Singh said, "He would roam around wearing the lab coat and stethoscope all the time". As he was not able to answer questions from the doctors in a satisfactory manner, he was arrested by the police. AIIMS officials said the impersonation was discovered after a complaint by doctors to authorities, alleging that they had identified an "impostor" who used the hospital as a platform to attend "different political and medical events".
Khurram has been charged under sections 419 (impersonation) and 468 (forgery for objective of cheating) of the Indian Penal Code.
He then started introducing himself as a junior resident to seniors, and as an undergraduate student to juniors. "He had even made his way to the WhatsApp groups", said Singh.
According to Singh, there are around 2, 000 resident doctors at AIIMS and it is quite hard to know each and every person individually, so Khurram used this issue to his advantage and never got caught by anyone.
There were also photographs of him with politicians.
